Energy-saving underwater attitude control system for manned deep submersible vehicle

Abstract

The invention relates to an energy-saving underwater attitude control system for a manned deep submersible vehicle. The energy-saving underwater attitude control system comprises a fixed depth control device and a longitudinal trim control device, wherein the fixed depth control device comprises a pressure-resistant water chamber and a buoyancy adjusting water chamber, a water injection pipeline of the pressure-resistant water chamber is connected with a through outboard water valve through a water injection valve, a drainage pipeline of the pressure-resistant water chamber is connected with the through outboard water valve through a drainage valve, a water pipeline of the buoyancy adjusting water chamber is communicated with the drainage pipeline of the pressure-resistant water chamber through a buoyancy adjusting water valve, and the pressure-resistant water chamber is communicated with a compressed air system; and the longitudinal trim control device comprises a head left inner water chamber, a head right inner water chamber, a tail left inner water chamber and a tail right inner water chamber, wherein the head left water chamber is communicated with the tail right water chamber through an air pressure distributor, the head right water chamber is communicated with the tail left water chamber through the air pressure distributor, the head left water chamber is communicated with the tail left water chamber through a left board water pipeline, and the head right water chamber is communicated with the tail right water chamber through a right board water pipeline. According to the energy-saving underwater attitude control system, the functions of stabilizing the underwater depth and balancing the longitudinal trim for the manned deep submersible vehicle can be realized, and the energy-saving requirements of the system are met.

Description

technical field [0001] The invention belongs to the technical field of underwater manipulation control of a manned deep submersible, and in particular relates to an energy-saving underwater attitude control system for a manned deep submersible. Background technique [0002] Manned deep submersibles have been widely used in marine surveys, underwater acoustic research, deep-sea resource exploration, submarine cable / optical cable maintenance, underwater lifesaving and salvage and other fields. [0003] Depth-fixed and trim-balanced are commonly used control conditions for manned deep submersibles during underwater fixed-point operations (such as resource exploration, environmental exploration, underwater salvage, etc.). During this period, the main propulsion device of the manned deep submersible stopped, the speed approached zero, and the rudder effect of the main elevator and rudder also approached zero. In order to stabilize the depth, balance the trim caused by the change...
